摘要:

砌体加固方案优选方法对实际工程遴选方案具有重要意义。为此建立了组合赋权法与TOPSIS法相结合的砌体结构加固方案优选方法,引入加固效费比模型,以效费比值为定量指标,以施工工期、施工技术、效果、整体效应4个因素作为定性指标,建立砌体结构抗震加固优选方案指标体系。以某教学楼为例,运用G1-COWA组合赋权法与TOPSIS法,求出该结构最佳加固方案为板墙加固方案。结果表明:所提出的优选方法具有一定的实用性和有效性,也适用于一般砌体加固改造工程; 优选方法能根据既有结构的基本信息,科学便捷地决策出最佳方案,为砌体结构的加固设计实施提供更科学的技术支撑。

Abstract:

The optimization method of the masonry reinforcement scheme is of great significance to the selection scheme of practical engineering.To this end,an optimization method for masonry reinforcement scheme based on combination weighting and TOPSIS methods is established.The reinforcement efficiency and the cost ratio model are introduced,and an optimization system is established,involving the quantitative indexes(efficiency and cost ratio)and the qualitative indexes(construction period,construction technology,outcome,overall effect).A case study of a teaching building is conducted by using the subjective and objective combination weighting method.And the best scheme of the structure is obtained:the slab wall reinforcement scheme.The results show that the proposed optimization method is practical and effective,and suitable for common masonry’s reinforcement and reconstruction.According to the basic information of the structure,the proposed optimization method is able to scientifically and conveniently give a reinforcement scheme,which provides technical support for the reinforcement design and implementation of the masonry structure.
